Abstract
The invention discloses a low cost air flow measuring method, which includes a high-capacity air passage, a low-capacity air passage, and two connecting air pipes connecting the high-capacity air passage and the low-capacity air passage. By utilizing the flowing feature of air, the air flow in the high-capacity air passage can be measured indirectly by measuring the air flow in a low-capacity air passage. The method can measure the air flow in the high-capacity air passage in an indirect manner, and solves the problem that the air flow in the high-capacity air passage is difficult to measure.
Description
Technical field
The invention belongs to the pipeline gas fields of measurement, particularly a kind of low-cost gas flow measurement method.
Background technology
In the pipeline gas fields of measurement, gas flow is large in the jumbo gas pipeline, is difficult to measure, and needs the mode of useful indirect measurement to measure gas flow in the jumbo gas pipeline, therefore, needs a kind of low-cost gas flow measurement method.
Summary of the invention
Order of the present invention is to provide a kind of low-cost gas flow measurement method.
The technical scheme that realizes above-mentioned purpose is: a kind of low-cost gas flow measurement method, comprise high capacity gas passage, low capacity gas passage and connect the high capacity gas passage be connected with the low capacity gas passage two connect tracheae P1, P2.
Above-mentioned a kind of low-cost gas flow measurement method, wherein, described connection tracheae P1 is at the initiating terminal of gas passage, and described connection tracheae P2 is at the tail end of gas passage, and the pressure in described high capacity gas passage and the described low capacity gas passage equates.
Above-mentioned a kind of low-cost gas flow measurement method, wherein, the flow of described large capacity passage is V, area is S, and the flow of described low capacity passage is V1, and area is S1, pressure in described low capacity passage and the described low capacity gas passage equates, V * S=V1 * S1 then under the described area S1 and the known situation of described low capacity gas passage area at the high capacity gas passage, can extrapolate according to the flow V1 of the low capacity gas passage of measuring the flow V of high capacity gas passage.
The invention has the beneficial effects as follows: the present invention can measure gas flow in the high capacity gas passage by mode indirectly, has solved the problem of high capacity gas channel gas flow measurement difficulty.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
See also Fig. 1, provided a kind of low-cost gas flow measurement method among the figure, it is characterized in that, comprise high capacity gas passage, low capacity gas passage and connect the high capacity gas passage be connected with the low capacity gas passage two connect tracheae P1, P2.
Connect tracheae P1 at the initiating terminal of gas passage, connect tracheae P2 at the tail end of gas passage, the pressure in high capacity gas passage and the low capacity gas passage equates.
The flow of large capacity passage is V, area is S, the flow of low capacity passage is V1, area is S1, pressure in low capacity passage and the low capacity gas passage equates, V * S=V1 * S1 then in the known situation of the area S1 of high capacity gas passage and low capacity gas passage area, can extrapolate according to the flow V1 of the low capacity gas passage of measuring the flow V of high capacity gas passage.
Below embodiment has been described in detail the present invention by reference to the accompanying drawings, and those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details among the embodiment should not consist of limitation of the invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
